I posted this comment on the NC forum in addition to here because there haven't been any responses to questions posed on this forum. I addressed it to the LEEDuser expert on that forum.

Dylan, you said in a comment in response to a PSI question that "LEED is about fixture efficiency selection rather than actual operating habits". That has been consistently the case before. For example, even though dual flush toilets are flushed by many users more than once, we have never had to deal with the behavior side of the potential savings provided by having one. So why the change here on metered faucets?

On commercial projects, this change is a brutal blow. There are very few places to get significant reductions against baseline flow rates. Urinals and lav faucets being primary among them. Adding more point thresholds opportunities feels like just adding insult to injury when there don't seem to be any realistic ways to get there with water fixtures alone.

It seems like there are times that LEED is all about reflecting the reality of usage and times when they subjectively decide the way things should be. I find this issue particularly interesting when you consider the 50/50 gender directive which is often not the reality of a specific project's actual usage but is always an assumption we are required to make. So much for consistency. What's your take on this issue?

PS. It's also very confusing to have a water reduction calculator that looks identical to v4 but is actually for v2009 and leaves the metered faucet calculation in there. A whole lot of room for error.
